A disjunctive site of Sympecma paedisca (Brau.) (Odonata: Lestidae) in Opole Silesia (south-western Poland)

2013

The occurrence of Sympecma paedisca in a small water body in the Limestone Quarry “Gorazdze” was recorded in 2010. This site is interesting because of the anthropogenic nature of ecosystem and its location 50 km west of the known range of the species.

The larva of Gomphus davidi Selys, 1887

1983

The female exuvia and last larval stage of Gomphus davidi Selys, 1887, a dragonfly endemic in the Middle East are described and figured. Distinctive characters of two sympatric Gomphus-species are provided.

Essays on the Performance, Subsidization and Internationalization of Social Enterprises

2020

Social enterprises are hybrid organizations that tackle societal challenges by using conventional business models. Being hybrid organizations means that social enterprises pursue dual objectives: social (developmental) and financial. By taking performance, subsidization and internationalization perspectives, this thesis contributes to understanding the hybridity of social enterprises and how this hybridity drives their general operations and key decisions such as foreign market selection and targeting strategy.

Organ Recovery Procedure in Donation After Controlled Circulatory Death with Normothermic Regional Perfusion: State of the Art

2020

The global shortage of organ donors will not be resolved solely by relying on donation after brain death. Expansion to use of donation after controlled circulatory death will be needed to address the shortfall of organs for transplantation. The processes of warm ischemia threaten the viability of organs obtained after controlled circulatory death, but these can be minimized by well-organized donation pathways and new techniques of in situ organ preservation, such as normothermic regional perfusion. The use of extracorporeal membrane oxygenation (ECMO) devices for normothermic regional perfusion in liver transplantation can help reduce rates of biliary complications, ischemic type biliary le…

Immunocompetence and resource holding potential in the damselfly, Calopteryx virgo L

2004

It is generally believed that resource holding potential reliably reflects male quality, but empirical evidence showing this is scarce. Here we show that the outcome of male-male competition may predict male immunocompetence in the territorial damselfly, Calopteryx virgo (Odonata: Calopterygidae). We staged contests between 27 pairs of males and found that winners of the contests showed higher immunocompetence, measured as encapsulation response, compared with that of losers. Furthermore, the winners had larger fat reserves. We also collected 29 males that had not been used in staged contests, and found that in these males encapsulation response correlated positively with an individual’s fa…

TOPOLOGICAL GAUGE THEORIES FROM SUPERSYMMETRIC QUANTUM MECHANICS ON SPACES OF CONNECTIONS

1991

We rederive the recently introduced $N=2$ topological gauge theories, representing the Euler characteristic of moduli spaces ${\cal M}$ of connections, from supersymmetric quantum mechanics on the infinite dimensional spaces ${\cal A}/{\cal G}$ of gauge orbits. To that end we discuss variants of ordinary supersymmetric quantum mechanics which have meaningful extensions to infinite-dimensional target spaces and introduce supersymmetric quantum mechanics actions modelling the Riemannian geometry of submersions and embeddings, relevant to the projections ${\cal A}\rightarrow {\cal A}/{\cal G}$ and inclusions ${\cal M}\subset{\cal A}/{\cal G}$ respectively. We explain the relation between Donal…

Rapporti di reggenza? Una descrizione ambivalente nella tradizione grammaticale tardoantica e medioevale

2023

This study aims to shed light on the historical development of a linguistic theory with reference to syntax in Late Antiquity and the Middle Ages, through an investigation of grammatical works related to Donatus, since a reflection on syntax emerges from the commentaries and from other grammatical works connected with his artes. This investigation focuses on the description of the government relation between praepositio and casus, through a preliminary collection of the occurrences of both terms with the Cross Database Searchtool of Brepols Publishers as a digital tool, and based on a textual analysis of the de praepositione sections included in a selection of grammatical works ranging from…

Impacts of piscicide-induced fish removal on resource use and trophic diversity of lake invertebrates

2022

Chemical eradication of non-native species has become a widely used method to mitigate the potential negative im- pacts of altered competitive or predatory dynamics on biodiversity and natural ecosystem processes. However, the re- sponses of non-target species can vary from rapid full recovery to delayed or absent recolonization, and little is known about the potential shifts in resource use and trophic diversity of native species following chemical treatments. We used a before-after-control-impact approach to study the effects of rotenone piscicide treatment on abundance and tro- phic niche of benthic invertebrates in three untreated and three treated lakes in central Norway, the latter gr…
